A twice bent pipe 25', through which the heavier liq-I its lower horizontalbranch 231 and through short lateral pipes 22 with the different compartments of the funnel. The pipe 25 contains a stop valve 24. On the outside ofthe funnel agauge tube 26 is arranged through which the level of the denser liquid can be .nel. The bottom of this receptacle is formed to with discharge apertures which are protect- V ed by strainers 28. I i

The action is as follows:

" Liquid filled into the receptacle-27*will be separated in the latter from its, coarser sediment and thenfed 011 to the hooolif From the latter, the liquid passes through' a the apertures 16, and over the edge of the" hood into the outer funnel compartment 7 whence it gradually flows into the other com partments and over the edges of the partitions towards the strainers 7 and 19. The partitions bathe the liquid and check the rush. Solid particles suspended in the liquid will be precipitated in the compartments in order of size, the heavier particles being collected in theouter, more disturbedcompartments, and the lighter particles in the inner, calmer ones. Theheavierliquid also settles at the bottom ofthe funnel andcan be drawn oil through the pipe 25. The level of the heavy liquid can be observed through the gauge 26 and can be regulated by an adjustment of the valve 2* so as to throttle the discharge. The light liquid rises under the hood a and passes through the strainers T and 19 and into the cylinder and thence through the valve 12 into the sleeve 5 and into the discharge stem 2. The operation is continuous, the two liquids being separated and both discharged at the same time.

If only a small proportion of heavy liquid is contained in the mixture, the valve 2st can be closed during the operation and only opened as occasion demands for the discharge of the heavy liquid.

By a combination of several devices of this kind, several liquids in mixture can be separated the lightest liquid being separated oil in the first tunnel and the others discharged together through the pipe into the second tunnel in which the next lighter liquid is divided off, and so on in succession.

I claim:

1. In a device of the character described for separating and straining liquids, the combination with a tunnel having a discharge stem which projects back into the funnel body, of strainers supported in a vertical position above the level of the stem, a protecting hood supported above the strainers, a valve arranged in the upper end of the stem so that itcan be adjusted for regulating the inlet to the same, and an upright tube extending above said hood as a guide and support tor the valve.

2. A device according to claim 1 wherein the strainers are cylindrical and concentric.

3. The structure claimed in claim 1 including a screw spindle connected to the valve and guided in the upright tube, a spring tending to close the valve, and a milled adjusting nut arranged on the spindle so as to support the valve in opposition to the spring by abutment against the upper end of the tube.

The structure claimed in claim 1 and circular partitions arranged below the hood so as to form a plurality of concentric overflow compartments.

5. The structure claimed in claim 1 including circular partitions arranged below the hood so as to form a plurality of concentric overflow compartments, a pipe communicating with said compartments for discharging their contents, and a stop valve in said pipe.
